<div id="cls-Ext.data.Types"></div>/**
 * @class Ext.data.Types
 * <p>This is s static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.<p/>
 * <p>The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.</p>
 * <p>Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:</p>
 * <div class="mdetail-params"><ul>
 * <li><code>convert</code> : <i>Function</i><div class="sub-desc">A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the collowing parameters:
 * <div class="mdetail-params"><ul>
 * <li><b>v</b> : Mixed<div class="sub-desc">The data value as read by the Reader, if undefined will use
 * the configured <tt>{@link Ext.data.Field#defaultValue defaultValue}</tt>.</div></li>
 * <li><b>rec</b> : Mixed<div class="sub-desc">The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.ArrayReader ArrayReader}), an object
 * ({@link Ext.data.JsonReader JsonReader}), or an XML element ({@link Ext.data.XMLReader XMLReader}).</div></li>
 * </ul></div></div></li>
 * <li><code>sortType</code> : <i>Function</i> <div class="sub-desc">A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.</div></li>
 * <li><code>type</code> : <i>String</i> <div class="sub-desc">A textual data type name.</div></li>
 * </ul></div>
 * <p>For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties <code>lat</code> and <code>long</code>, you would define a new data type like this:</p>
 *<pre><code>
// Add a new Field data type which stores a VELatLong object in the Record.
Ext.data.Types.VELATLONG = {
    convert: function(v, data) {
        return new VELatLong(data.lat, data.long);
    },
    sortType: function(v) {
        return v.Latitude;  // When sorting, order by latitude
    },
    type: 'VELatLong'
};
</code></pre>
 * <p>Then, when declaring a Record, use <pre><code>
var types = Ext.data.Types; // allow shorthand type access
UnitRecord = Ext.data.Record.create([
    { name: 'unitName', mapping: 'UnitName' },
    { name: 'curSpeed', mapping: 'CurSpeed', type: types.INT },
    { name: 'latitude', mapping: 'lat', type: types.FLOAT },
    { name: 'latitude', mapping: 'lat', type: types.FLOAT },
    { name: 'position', type: types.VELATLONG }
]);
</code></pre>
 * @singleton
